A **HTTP Server with WebDav** active is a server where you probably can **update, delete, move, copy** files. **Sometimes** you **need** to have **valid credentials** (usually check with HTTP Basic Authentication). You should try to **upload** some **webshell** and **execute** it from the web server to take control over the server.\ Usually, to **connect** a WebDav server you will need valid **credentials**: [**WebDav bruteforce**](../../generic-methodologies-and-resources/brute-force.md#http-basic-auth) _(Basic Auth)_. Other common configuration is to **forbid uploading** files with **extensions** that will be **executed** by the web server, you should check how to **bypass this:** * **Upload** files with **executable extensions** (maybe it's not forbidden). * **Upload** files **without executable extensions** (like .txt) and try to **rename** the file (move) with an **executable extension**. * **Upload** files **without executable extensions** (like .txt) and try to **copy** the file (move) with **executable extension.** ## DavTest **Davtest** try to **upload several files with different extensions** and **check** if the extension is **executed**: ```bash davtest [-auth user:password] -move -sendbd auto -url http:// #Uplaod .txt files and try to move it to other extensions davtest [-auth user:password] -sendbd auto -url http:// #Try to upload every extension ``` Output sample: ![](<../../.gitbook/assets/image (19) (1).png>) This doesn't mean that **.txt** and **.html extensions are being executed**. This mean that you can **access this files** through the web. ## Cadaver You can use this tool to **connect to the WebDav** server and perform actions (like **upload**, **move** or **delete**) **manually**. ``` cadaver ``` ## PUT request ``` curl -T 'shell.txt' 'http://$ip' ``` ## MOVE request ``` curl -X MOVE --header 'Destination:http://$ip/shell.php' 'http://$ip/shell.txt' ```

The **WebDav** does **not allow** to **upload** or **rename** files with the extension **.asp**. But you can **bypass** this **adding** at the end of the name **";.txt"** and the file will be **executed** as if it were a .asp file (you could also **use ".html" instead of ".txt"** but **DON'T forget the ";"**). Then you can **upload** your shell as a ".**txt" file** and **copy/move it to a ".asp;.txt"** file. An accessing that file through the web server, it will be **executed** (cadaver will said that the move action didn't work, but it did). ![](<../../.gitbook/assets/image (18) (1) (1).png>) ## Post credentials If the Webdav was using an Apache server you should look at configured sites in Apache. Commonly:\ _**/etc/apache2/sites-enabled/000-default**_ Inside it you could find something like: ``` ServerAdmin webmaster@localhost Alias /webdav /var/www/webdav DAV On AuthType Digest AuthName "webdav" AuthUserFile /etc/apache2/users.password Require valid-user ``` As you can see there is the files with the valid **credentials** for the **webdav** server: ``` /etc/apache2/users.password ``` Inside this type of files you will find the **username** and a **hash** of the password. These are the credentials the webdav server is using to authenticate users. You can try to **crack** them, or to **add more** if for some reason you wan to **access** the **webdav** server: ```bash htpasswd /etc/apache2/users.password #You will be prompted for the password ``` To check if the new credentials are working you can do: ```bash wget --user --ask-password http://domain/path/to/webdav/ -O - -q ```
